Description

Injection molding insulation module connecting copper bar

Technical Field

The utility model relates to a new forms of energy technical field, concretely relates to insulating module of moulding plastics connects copper bar.

Background

The battery module is formed by connecting a plurality of battery cores through a certain series-parallel relation and converges to the positive and negative electrodes for output. And the modules are connected in series and parallel to form the battery box. Because the connection of single electric core adopts electrically conductive aluminium to arrange laser welding electric core more, and adopts the copper bar to connect usually between module and module, generally adopts soft copper to arrange technological realization such as connection at present. The soft copper bar is complex to process, needs multiple layers to be overlapped and welded together, has multiple post processes, and is easy to cause assembly interference due to the fact that two sides of a welding area are deformed after welding.

Therefore, an injection molding insulation module connecting copper bar is provided for overcoming the defects.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that an insulating module of moulding plastics connects copper bar is provided, it is bent through thickening copper sheet stack and is replaced the soft copper bar and need the diffusion welded mode for this connecting piece need not the diffusion welding, it is high to connect the face plane degree, and the connection area does not have the deformation, and the effectual assembly that has solved welding deformation and causes is interfered, and this kind of structure manufacturing cost is lower, and the current soft copper bar of production efficiency contrast is higher, has reduced the production defective rate simultaneously, more is fit for the volume production.

An injection molding insulation module connecting copper bar comprises a copper bar, wherein the copper bar is formed by overlapping a plurality of copper sheets; an insulating layer is arranged on the outer side of the copper bar; the insulating layer is injected on the copper sheet to obtain a coil material; and two ends of the copper bar extend out of the outer side of the insulating layer.

Preferably, the two ends of the copper bar, which extend out of the outer side of the insulating layer, are punched with connecting holes by using a die.

Further preferably, the number of the plurality of copper sheets is 2-20.

Further preferably, the thickness of each copper sheet is 0.3-0.5 mm.

Further preferably, the copper sheet is formed by pressing red copper T2.

Has the advantages that: the utility model discloses the purport lies in bending through thickening copper sheet stack and replaces soft copper bar and need the diffusion welding mode for this connecting piece need not diffusion welding, and it is high to connect the face plane degree, and the connection area does not have the deformation, and the effectual assembly that welding deformation caused of having solved interferes, the utility model discloses compare in soft copper bar, this kind of structure manufacturing cost is lower, and the current soft copper bar of production efficiency contrast is higher, has reduced the production defective rate simultaneously, more is fit for the volume production.
